To all whom it may concern:

Be it known that 1, MICHAEL DONALD COCK,' a subject of the King of Great Britain and Ireland, residin in the town of Powlett River, in the shlre of Phillip Island and VVoolamai, county of Mornington, State of Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in Agricultural. T ructors, of which the following is a. specifics-- tion.

This invention relates to an under-corriiige and its ipurtennnces, above which a. motor car is melted the tired wheels of which rotate the rear or propelling; whw-ris of'the said undercarriage.

Intbr: the orclim 1 motor car was unfit for on agricultural tractor its wheels licking the width and adhesion needful on plowed or soft ground. gfjuch vehicles thr ugh useful to e farmer foe-i pleasure or marketing purposes not well adapted for field traction or farm worlci The object this invoi'itizni to provide a suitable under arriage end its accessories ebove. which a motor car can be safely pieced. or equally as safely removed. No

alteration wlnitever needed to the car, no'

part of wl'iich is called upon to perform any other, duty than that for which it was designed. When on the top of the undercarriage the motor can be used to propel the tractor or it may be employed for the driving of any mochil'iery about a farm.

Provision may be made for driving a. fan whereby the radietin water is cooled when the motor car is per orming farm work or trslveling slowly.

Referring to the drawings which form a part of this specification Figure 1 is a side elevation of an under-- carriage the fore wheels of which have been removed and the front of which rests on the-ground ready to receive the car. Fortionsiire broken. away for convenience of illustijation.

F'g. 2 is a part sectional front view showin% a. lateral slide and a. wheelwa-y.

ig. 3 is a side elevation showing the front of the under-carriage :l'reme elevated and in broken lines the rear wheels of a car in position for work.

Figst is a plan of Fig. 3, the rear wheels and axle of the car being shown in broken li n'e|s1.,f v I On'refer'cnce tb thedrewings it will driven seen that the invention includes rear tractor wheels 2 united by a rear axle 3 turnin in bearings, 4:. To each wheel is attache an internally toothed ring 5.

The front wheels 6 are united to a front axle 7 beneath the center of which is a king bolt pin 8. Above the saidfront'axle is an upward extension 9 at the top of whichis a cup 11. To the said axle are attached steering hooks 12.

To the said king bolt pin is attached the lower end of a king bolt stay 1 1, the upper end. of" which is pivoted to on under-carriage hereinafter referred to.

The said undercarriage includes two outer longitudinal members 15 and two innor-lqmgitudinal members 16. These may be united by a. front cross piece 17 and a back cross piece 18. They are also stayed to each other by diagonal braces 19. To the back cross piece or an extension therefrom may be attached any form of draw hook or hooks or bar or bars. Protruding from beneath the front cross piece 17 is a ball 21 which fits into the cup 11.

Upon the rear part of the longitudinal members are attached bearings 23. l hese I are capable of movement backward or for-.

upon which are two tire driven wheels-29 provided with suitable internal friction clutches. Around each tire driven wheel is a 31. This may be secured to the said wheel by a. web 32 orin any other way.

The said flange is adjustable elong'the wheel to. suit different widths of motor cars; Slid ably mounted on the shafts 28 are toothed wheel's Also secured to the said shaft are one or more driving pulleys 33. Mounted on a, counter shaft 36 at each side at the under-carriage and adaptedito ong. the toothed wheels 34 are toothed whose 40. The toothed wheels 34 and. 40 provide change speed gear forthe undercarriage.

Mountedon the counter shaft 86 and 011- gaging the internallytoothed rings 51 em dnving pinio'n's 44.

' Restinglupon'the idle rollers and ;there eels are the mal wheels-85 o' it motor car. Ilpstcnding, above. the? underj carriage is a steerin handle 37. This may be so situated that t e driver can sit in the motonear and control the engine and steer the tractor. It is secured to the top of a vertical steering shaft 38 turning in a bracket 39. At the bottom of the said vertical steering shaft is a first bevel wheel/l1 turning a second bevel wheel 42 upon a horizontal steering shaft 43 turning in bearings attached to the under-carriage.-

To the front hooks 12 upon the front axle are attached the front ends of steering ropes or chains 45. The rear ends are attached to the horizontal shaft 43.

v Attached above the longitudinal members of the under-carriage in any well known way and having their upper ends preferably attached to a bearer 47 are wheelways.

I Each wheelway has a bottom 48 and sides 49. Through one of the sides in each wheelway is formed a slideway 51. This permits the passage of a slide 52, which slide is preferably of sheet metal. It has an outer depending portion 53 through which is an adjusting screw hole. Attached underneath the bottom is a stationary nut 54. In this nut turns an adjusting screw 55 which passes through an adjusting screw hole in the outer depending portion 53. This screw is turned by a spanner, a hand wheel or in any other way.

Suitable attachments can be provided whereby from one of the pulleys upon the counter shaft a" belt drives a fan which fan causes a current of air upon the radiator of the motor car. v

This invention is operated as follows When a. motor is to be p aced on the top of the under-carriage the ront portion of the under-carriage by a screw ack or other arrangement is lifted so that the ball 21 is lifted from the cup. The king bolt pin stay is detached from the axle or from the under-carriage and the steering ropes or. chains are unhooked from the axle. The said front axle is then pulled outwardly and the front portion of the under-carriage lowered to the ground The rear of the motor car is then backed toward the lower ends of the wheelways and the car moved upwardly until its driving wheels "35 glide down the wheels rest upon the slides.-

tire driven wheels 29. and rest between them and the idle rollers 25. The adjusting slides 52 uponthe wheelways are so positioned that, when the rear wheels of the motor car are in the position mentioned the front by the adjusting screw 55 can be moved to the right or to the left and any obliguity th between-the axle of the motor car an shaft 28 can be removed. When the car is in position above the under-carriage it is j secured thereto by straps'or the like. The

front portion of'thesaid under-carriage is then elevated andthe front .axle' reposi- ,ingthe front axle with the under-carri.

These slides tioned. When the en 'ne of the motor car is started it drives t e tire driven wheels Y .80 1.

movable to and from the tire driven wheels and. adjustable flanges-carried by the tire driven wheels and the idle wheels.

I 3. Inagricultura-l tractors, the combination with a motor car, of an under-carriage sup orting said car, tire driven wheels carrie by the under-carriage, wheel ways leading from the front of the under-carriage to the tire drivenwheel's, idle wheels movable to and from the tire driven wheels, a flange mbunted on the periphery of each tire. driven wheel, means for laterally adjlistily'r each i I I and, rear Wheels supporting said frame,

gears mounted on the rear wheels, alined horizontal shafts n'iounted on the frame, a flanged friction wheel mounted on each shaft, a counter shaft mounted in advance of each rear wheel, a gear on each counter shaft meshing with the gears on the rear wheels, gearing between the respective horizontal shafts and the respective counter shafts, fl'rimged idle wheels in rear of and in alinement with the friction wheels, giiiideways extending forwardly from the friction wheels, and means for steering the'front wheels.

5. In an undercarriage for the purpose described. the combination of a frame, front and rear wheels supporting the frame, a pair of l(.)l'\gltll(lll1zll guides on the frame, a pair of horizontal alined shafts mounted on .first mentioned flanged wheels,

each slide and holding same in adjusted position. i

6. In an under-carriage for the purpose described, the combination of a frame, front and rear wheels therefor, a pair of longitudinal gnide-Ways on the frame, a pair of flanged wheels at the rear of and in alinement with the guide-ways, each flanged wheel being mounted independent of the other, gearing between the respective flanged wheels and the respective rear Wheels, and flanged wheels mounted on the frame independently of each other in lon itudinal alinement with the first mentionet flanged wheels.
